I'm very skeptical about energy drinks and picky about pre-workout drinks. Some have only given me energy for a short time, some give me a crash, and some give me bad reactions such as shakes or the prickly feeling. But I'm a fan of Orange Theory Fitness so I figure why not try the drink. I'm very surprised and pleased to say I'm highly satisfied with this drink! It doesn't give me any negative reactions and it lasts a while; well for me! I replaced coffee in the morning for this and I don't think I'll ever have coffee again lol Also without even trying, I've dropped two pounds in a week. I really think it's because it does what it says and because I received more energy, I was getting off my butt and finishing my tasks at home at work hence burning more calories! So far it's been a few weeks so hopefully I'll continue loving it!

Delicious, tastes like a SNOW CONE!! And because it's not carbonated, you can add water to dilute it & get a steady stream of caffeine all day long rather than drinking it all in one sitting (which I don't recommend unless you're REALLY tired, lol.) These work! And they taste great full strength as well as diluted.

I have been drinking Celsius every single day since 2004. It's how I start my day"” EVERY DAY. And after all these years now I've got my wife drinking it, too. I wish they would bring back some of the original flavors (ginger ale and lemon lime were my favorites) but orange and watermelon are good, too. If you're looking for natural energy with no sugar, crashes or jitters"”this is it.

Celsius energy drinks are the only energy drinks I will consume. If you're like me and don't like the typical tastes of other energy drinks (red bull, monster, etc), I would highly recommend trying these. The sparkling versions are the best and I sip on one throughout the day, just 1 as it has so much caffeine and 2 makes me too jittery. However, if you have trouble sleeping, then I wouldn't suggest drinking these for at least 6 - 8 hours before bedtime as it will almost certainly keep you up. The sparkling grape is my favorite, second best is the wild berry, third is the orange. Cola is the absolute worst flavor. Tastes like a generic soda that's been left open to go flat and has lost most of the flavor. The watermelon is okay, but tastes the most artificial. I noticed when I started to perspire or feel warmer than usual, for me, it was working to boost metabolism and burn some calories. These are easy to build up a tolerance to the caffeine and lose some of the energy benefit after 1 - 3 months of daily use. So you might consider skipping a day every now and then to consume a smaller amount of caffeine to scale back on the tolerance and then come back to these for renewed benefit.

Got hooked on these after my trainer introduced me to them! Great flavor, LOTS of energy plus a fat burner. Can't go wrong with watermelon. Also love peach and orange ones too!
